Abstract

The invention discloses an end face driving bevel gear tooth-shaped connecting structure which is characterized in that the outer end of the end face of a component I is an externally tangent inclined annular inclined face I, a plurality of inclined bevel gears I are evenly and outwards arranged on the annular inclined face I in a protruding mode, bevel grooves I are formed between the bevel gears I, and bevel gears are formed by the bevel gears I and the bevel grooves I; the outer end part of the end surface of the part II is a concave and inclined ring-shaped inclined surface II; the inclined plane II and the inclined plane I have the same width and inclination angle; conical grooves II which are the same as the conical teeth I in number and are matched with the conical teeth I are uniformly and inwards concavely formed in the inclined surface II, conical teeth II matched with the conical grooves I are arranged among the conical grooves II, and each conical tooth II and each conical groove II form an inwards concave bevel gear; and the component I and the component II are axially compressed, and the bevel gear and the concave bevel gear are completely meshed together. The invention has the advantages of large stress area, good transmission stability, strong wear resistance and long service life; the self-centering function is achieved, jumping generated by rotation is avoided, noise is low, and the self-centering rotary joint is suitable for being used in occasions with higher rotating speed and higher power rotary connection.

Description

technical field

[0001] The invention relates to an end-face driving bevel gear tooth-shaped connection structure. Background technique

[0002] The face gear mainly transmits motion and power through the continuous meshing of the teeth. It is one of the most widely used transmission methods in modern equipment and the automotive industry. At present, the face teeth are straight grooves and straight teeth made directly on the end face of the shaft. In order to It does not cause changes in other parameters of the shaft, the length of the teeth and grooves is shorter, the force-bearing surface becomes smaller, the transmission stability is poor, the wear resistance is poor, and the service life is short. And the end faces of the two end face teeth meshed together are all planes, and the flatness of the planes is poor, resulting in more contact positions of points or lines, which further causes the force bearing surface to become smaller, poor transmission stability and wear res...
